Models of Language and Communication - PSYC 51.17 Course materials for PSYC 51.17: Language Models from Scratch - Dartmouth College

Excited to be teaching a new undergraduate course on Models of Language and Conversation this term!

Check it out here: context-lab.com/llm-course/

I've added lots of fun interactive demos of chatbots and NLP techniques that let students dig into the approaches.

This paper had a pretty shocking headline result (40% of voxels!), so I dug into it, and I think it is wrong. Essentially: they compare two noisy measures and find that about 40% of voxels have different sign between the two. I think this is just noise!

Quantifying memory recall is hard! Luckily, natural language processing (incl. #LLMs) offers new, automated, and scalable ways to do that!

New paper with @mujianing.bsky.social & @prestonlab.bsky.social! We propose a simple model for human memory of narratives: we uniformly sample incoming information at a constant rate. This explains behavioral data much better than variable-rate sampling triggered by event segmentation or surprisal.

The House committee for NSF/NASA/NOAA is meeting tomorrow (Tuesday) at noon ET. Now would be a good time to call anyone on this list & tell them to keep science funding at full 2025 levels. You can remind them that 75% of voters want tax-funded science and they're concerned about the impact of cuts.

Music-evoked reactivation during continuous perception is associated with enhanced subsequent recall of naturalistic events Music is a potent cue for recalling personal experiences, yet the neural basis of music-evoked memory remains elusive. We address this question by using the full-length film Eternal Sunshine of the Spotless Mind to examine how repeated musical themes reactivate previously encoded events in cortex and shape next-day recall. Participants in an fMRI study viewed either the original film (with repeated musical themes) or a no-music version. By comparing neural activity patterns between these groups, we found that music-evoked reactivation of neural patterns linked to earlier scenes in the default mode network was associated with improved subsequent recall. This relationship was specific to the music condition and persisted when we controlled for a proxy measure of initial encoding strength (spatial intersubject correlation), suggesting that music-evoked reactivation may play a role in making event memories stick that is distinct from what happens at initial encoding. ### Competing Interest Statement The authors have declared no competing interest. National Institutes of Health, https://ror.org/01cwqze88, F99 NS118740, R01 MH112357

Music is an incredibly powerful retrieval cue. What is the neural basis of music-evoked memory reactivation? And how does this reactivation relate to later memory for the retrieved events? In our new study, we used Eternal Sunshine of the Spotless Mind to find out. www.biorxiv.org/content/10.1...

Pleased to say "Space, Time, and Memory", an academic book by Oxford University Press edited by the inimitable Lynn Nadel & Sara Aronowitz is now out.
I contributed a chapter, "Memory and Planning in Brains and Machines".

Yes, that would be my default setting. But as I used the AI-agent over time it could become graded. I purchased your book based on an ad that I saw on your website, and I really enjoyed the book. So perhaps I would instruct my AI-agent to relay certain ad information but not others?

05.05.2025 16:18 โ€” ๐Ÿ‘ 2    ๐Ÿ” 0    ๐Ÿ’ฌ 0    ๐Ÿ“Œ 0

Presumably the AI-agent would still be able to view the ads and report back to their user if they came across something advertised which would be interesting/useful for their user.

I guess you are considering the case where the user explicitly tells the AI not to inform them of anything ad-related?

14.04.2025 17:47 โ€” ๐Ÿ‘ 106    ๐Ÿ” 15    ๐Ÿ’ฌ 2    ๐Ÿ“Œ 0

All I can say is that the subjective effect size of the difference is very large and beyond what I would normally question. Once I start to question the validity of such judgments, I don't know how I could trust the majority of my waking self-report.

14.04.2025 14:44 โ€” ๐Ÿ‘ 5    ๐Ÿ” 0    ๐Ÿ’ฌ 1    ๐Ÿ“Œ 0

I've (on occasions) had normal waking imagery that is vivid. That waking imagery is just like the vivid imagery that I (much more often) experience near sleep. I agree that I'm always comparing two past states here, which involves some kind of memory function.

14.04.2025 14:44 โ€” ๐Ÿ‘ 4    ๐Ÿ” 0    ๐Ÿ’ฌ 1    ๐Ÿ“Œ 0

I am close to aphantasic (~2 out of 7 visual and auditory). However, there is an exception: I experience visual and auditory imagery when I am on the edge of sleep. So I know what imagery is, and I just don't experience it at other times. I don't know *how* I could be so wrong in subjective report.
